A left rotation operation on an array of size shifts each of the array's elements unit to the left. For example, if left rotations are performed on array , then the array would become .
Given an array of integers and a number, , perform left rotations on the array. Then print the updated array as a single line of space-separated integers.
The first line contains two space-separated integers denoting the respective values of (the number of integers) and (the number of left rotations you must perform).
The second line contains space-separated integers describing the respective elements of the array's initial state.
Print a single line of space-separated integers denoting the final state of the array after performing left rotations.
1 2 3 4 5
5 1 2 3 4
When we perform left rotations, the array undergoes the following sequence of changes:
Thus, we print the array's final state as a single line of space-separated values, which is 5 1 2 3 4.
